The Magnetic Hold Down Heat Sealer

What makes our new heat sealer with magnetic hold down so good! Why is our new impulse heat sealer so good! To understand what makes our magnetic hold down heat sealer so good first we need to understand how a heat a sealer works and how it seals the lay flat tube or whatever material you wish to heat seal. Many people will have used the traditional heat sealer that sits on the bench or table top and is there ready to use whenever you need, or you may even be slightly better set up with a film unroller that easily un rolls either you lay flat tube or even shrink wrapping film if that is what you are using your heat sealing machine for (you get far better results from our small shrink wrap heat sealers but that’s another story!). Many people find that they are constantly changing wires or tapes just like the heat sealer spares kits that we supply, so the question is why do these sealing wires and heat proof tapes not last so long or why is the seal produced by the bar sealer so poor. The reason is that these machines are as they are called an impulse sealer meaning that when you pull down the arm of the heat sealer an impulse of low voltage electricity is applied to the heat sealing element which causes it to get warm. This process is controlled by time and not the actual temperature of the sealing element. Steve Holt What happens all too often is that the operator pulls the arm of the machine down and is unsure if the machine has sealed correctly and then immediately pulls the arm down again. This will cause a double pulse causing the sealing strip or wire to get warmer than the setting suggests, this then burns the wire out or burns the heat proof tape causing the film to stick and not seal, this then can tempt the operator into turning up the heat so as you can see the cycle starts no seal more heat more heat less seal etc etc. Ever heat seal made is made up from 3 factors Heat, Time and pressure take as many of these and automate them as much as possible and 3 things will happen. 1)The seal quality will improve 2) The machine will last longer meaning less money spent on heat sealer spares and 3) Productivity and items sealed per hour will increase !. With any heat sealing application be it a 2mm wide seal or even sealing films ready for shrink wrapping it takes more than speed to increase productivity. So what is the answer? 1)Take your time and keep the sealing impulse as low as possible this may sound counterproductive but it will not take much stoppage through trying to work to quickly to get this time and cost back. 2) Invest in a Semi automatic heat sealer like our SMS range that you can view here. Although more expensive these machines go on and on and on. 3) Try one of our great Magnetic hold down super sealers. For not much more money than a basic heat sealer we can supply you with one of the heat sealers that will hold down by itself before releasing leaving you with the perfect seal.
